Trust me Fat, if you are stuffing a HDD like that into a comp $1580 is barely gonna be noticeable in the final price tag. Plus your rig will be liquid nitrogen cooled and possibly have a set of lungs lol...

I've known guys that will spend an extra $500 or so dollars on the latest and greatest processor that is actually only like .1Ghz better than the "Step Down"...These type of guys are insane when they are building a new rig.
